Evaluation of Coil Selection Algorithms for Body Navigators

Respiratory
navigator techniques rely on the processing algorithm to accurately extract
motion information from the navigator echo. When using a multi-channel
receive coil, the selection of which channel to use can influence the success
of the navigator processing algorithm. By selecting a subset of channels, the
coil sensitivity modulation of the navigator signal can be exploited to
enhance the prominence of features of interest while also improving real-time
processing efficiency. In this work, we evaluate the suitability of different
coil selection methods for use with navigator processing and propose a method
based on a matched filter.
